Abstract
Alum, also known as Potash, is used to can pickles. Alum powder was used to create seed crystals. The seed crystal was hung in a jar submerged in distilled water with alum powder dissolved to attempt to grow an Alum crystal over the Spring semester. Three different concentrations were used to determine changes associated with crystal growth and quality. Numerous strategies were employed throughout the semester as growth methods worked and did not work.
